The Biological Activity of Selected Cyclic Dipeptides

open access: yesJournal of Pharmacy and Pharmacology, 1998
Abstract Cyclic dipeptides are widely used as models for larger peptides because of their simplicity and limited conformational freedom. Some cyclic dipeptides have been shown to be antiviral, antibiotic and anti-tumour. The aim of this study was to determine the biological activity of four cyclic dipeptides synthesized in this ...

Fragmentation of 2,5-diketopiperazine cyclic dipeptide ions

open access: yesTechnical Physics, 2022
The mechanism of radiation damage to 2,5-diketopiperazine (DKP, C4H6N2O2) molecules in the gas phase upon interaction with He2+ ions with an energy Ep = 4 keV/u has been investigated. The relative cross sections of various elementary processes occurring in single collisions of DKP with ions have been measured for the first time.

Enzymatical and microbial degradation of cyclic dipeptides (diketopiperazines) [PDF]

open access: yesAMB Express, 2013
Diketopiperazines (DKPs) are cyclic dipeptides, representing an abundant class of biologically active natural compounds. Despite their widespread occurrence in nature, little is known about their degradation. In this study, the enzymatical and microbial cleavage of DKPs was investigated.
